The influence of SMA on buckling of composite laminates by varying the SMA fiber spacing was studied. Two ways to embed SMA fibers into composite laminates (namely: Active Property Tuning (APT) method and Active Strain Energy Tuning (ASET) Method) were considered. The results show that the ASET method is much better than the APT method in improving the buckling performance of the plate. When the SMA fibers are concentrated in the center area of the plate, the buckling load of the plate will be improved significantly. If the stiffness of the SMA layer is lower than other layers, the influence of the SMA on the buckling load of the plate will become subordinate.
